- Figure 1. A simple oven circuit, heated by both R2 and Q2. The NTC thermistor Th1 provides feedback, the set point being determined by R1. Note how critical components are thermally tied together as they are all built onto the TO-220 package, as shown in the photos
- Figure 2. While electrically the same as Figure 1, this brings out most circuit nodes to help with experimentation and monitoring, including the LEDs on "pin 3"
